PORTABLE DERAIL.

Specification of Letters Patent.

Application filed March 15, 1909.

Patented Mar. 28, 1911. Serial No. 483,365.

To all whom it may concern.

Be it known that I, STANLEY W. HAYES, a citizen of the United States of America, residing at Geneva, in the county of Ontario and State of New York, have invented certain new and useful Improvements in Portable Derails, of which the following is a full, true, and concise specification.

This invention is a portable derail, that is to say, a wheel derailing device having no permanent connection to the road-bed but adapted to be carried about and applied to the rail at such point as may be desired, and the invention resides in the construction,

- relative arrangement and operation of parts as hereinafter described, whereby the facility and rapidity with which the device can be applied to the rail is promoted and the security of its attachment is rendered adequate to withstand the shock of derailment and whereby the device may be attached with equal facility and effect to rails of widely varying kind or size and whereby, also, certain other features of advantage in the practical use of the device are secured, as will be plain to those familiar with this art.

In the drawings forming a part hereof, Figure 1 is an end elevation of a form of embodiment of the invention with the derail block member and the rail shown in section; Fig. 2 is a similar view illustrating the device applied to a rail of larger dimension; Fig. 3 is a top plan of the device; Fig. 4: is a section, Fig. 5 an end elevation, and Fig. 6

I a plan of a modification of construction.

The part marked 1 is the derail block member which is cast or otherwise formed with a diagonal rib and groove 1 on its upper side adapted to lift the flanges of passing wheels and guide them over the outside of the rail. The forward portion of the derail block member which overlies the head of the rail and extends somewhat beyond it, is formed, on its under side, with a substant-ially flat or plane bearing, marked 2, intended to engage the top or tread of the rail. The said bearing is preferably of a width equal to or greater than the width of the tread of the largest standard rail, and may be constituted of the edges of a series of intercellular partitions on the under side of the block, it being customary to cast or form the derail block member in this manner for economy of weight and metal.

The dotted lines in Fig. 3 represent the cellular formation. A depending shoulder bottom,

3, formed on the under side of the member, constitutes the inward or rearward boundary of the said bearing and is adapted, by its engagement with the side of the rail head, to determine a proper position of the rib and groove with reference to the flanges of the wheels which are to be derailed. The shoulder 3 may be continuous in length, or comprised of a number of depending parts or projections, according to the type of construction, and the position which it determines by engagement with the rail is independent of the size or height of the latter, inasmuch as the wheel flanges in any case travel along the side of the rail-head in the same vertical plane as the shoulder. To insure the security of the position thus de termined the invention in its preferred embodiment contemplates the application of the clamping or securing force so that a portion of the pressure will be resolved in a lateral or inclined direction, which will hold the shoulder firmly against the railhead, but such direction of the clamping pressure is not essential to the effective operation of the device and the clamping force may be exerted wholly in a vertical direction.

The complementary clamp member of the device is comprised of one or more jaws 4;, each of which has a comparatively slender formation and is tapered so as to be capable of being readily thrust between the base of the rail and the subjaoent ballast or soil without special excavation of the latter, and the ends of the jaws are hook-shaped and adapted to embrace or grasp the edge of the base flange of the rail. These jaws may be formed as a single clamp or jaw member, if desired, but their separate format-ion, as illustrated in the drawings, is preferred, because of the greater facility thereby provided for inserting them under the rail. Two jaws will ordinarily be sufficient, one at each end of the derail block, so that they can thus be used to grasp the rail on opposite sides of a tie. The clamp member, whether formed of one or several parts or jaws, is connected with the other clamp member, that is, the derail block member, with a sufficient freedom for vertical movement of the one relatively to the other, to accommodate the engagement of the two members with the opposite sides, or top and of different sizes of rails, as will be plain from an inspection of Figs. 1 and 2, wherein the device is shown as attached to rails of extreme sizes. The connection rcterred to prelerably provides for relative pivotal n'iovement in a vertical direction, and is etlected by the clamp screws (3, which are the power means by which the elan'lping pressure is produced.

As shown in Figs. 1 to 3-3, the clamp screws (3 are thraaded into terminal bosses 5 at the inner ends of the jaws, in alinemcnt with the hooks at their free ends, and their heads 7, which are relatively large and rounded, are seated in dished or partially countersunk recesses in the derail block member, the engagement resembling that of a. ball and socket joint, so that the jaws t may thus receive a limited pivotal movement for the purpose stated. I In the modification shown in Figs. 4, 5 and G, a greater range of relative pivotal n'ioven'ient is provided by pivoting the jaw or jaws 4- of this form upon a part, such as b, which constitutes the nut or nuts of the clamp screws 6*. In this form of construction the screws need have no special provisions for vertical movement with respect to the derail block member.

As thus constructed, the device includes, further, a means for supporting it against the tendency to turn or swivel on the rail under the impact of wheels encountering the end of the groove 1*. This means consists of a fixed vertical bearing for the clamp members at the side of the rail, preferably upon the top of a tie some distance from therail, and includes an adjustable bearing device, such as the screw 9, which is, in fact, a leveling screw, threaded into one of the members, preferably the derail block member, with its lower end provided with a flange or foot for engaging the tie. By rotating this screw or power device, the side of the derail block member may be raised or lowered to a level position, corresponding to the height of any size of rail, and the sup porting bearing it thus provides will manifestly be adequate to maintain the derail in a fixed position. Operating handles 10 and 11 are pivoted respectively to the clamp screws 6 and the leveling screw 9, and such handles are adapted to be mutually interlocked, as by passing the terminal eyes of the clamp screw handles over the end of the handle of the leveling screw, in which position a padlock may be looped through the end of the latter lever, whereby the whole device can be permanently locked to the track. The operating handles 1O" and 11 of the modified form of Figs. 4 to 6 are confined within perforations in the heads of their respective screws but with suflicient looseness to permit of the same interlocking operation.

In operation the jaw members, having been first screwed down, their clamping screws are worked under the rail and hooked on the edge of the base flange, and the leveling deviee is then operated until the derail blot-k assumes a horizontal or any desired position, whereupon the clamp screws are tightened and the members are drawn together in clamping engagement upon the rail and road-bed, in obvious manner. In such position the overhanging 'liorward por tion of lhe derail block will project beyond the plane of the hooks on the ends of the jaws and prevent the derailed wheels from striking and injuring them. Thrust on the derail parallel to the rail is resisted by the binding action of the clamp members upon the rail, and the portion of the device which extends below the rail constitutes a further support. by engagement with the side of one of the track ties. IVhen the handles of the several screws have been confined against rotation as by the use of a padlock, it will be impossible not only to remove the derail but also to loosen it. or change its position on the rail.

I claim the following:
